Utah Mammoth Secures Promising Goaltender Sebastian Cossa with New Contract

The Utah Mammoth have signaled their commitment to the future by acquiring goaltender Sebastian Cossa from the Detroit Red Wings. Just days after completing the trade, which involved sending the 23rd overall selection in the 2026 NHL Draft to Detroit, the Mammoth announced Cossa has signed a two-year contract valued at an average annual rate of $2 million. This contract solidifies Cossa’s role as a key component in the organization’s long-term plans for goaltending.

Cossa, who arrives in Utah after honing his skills with the American Hockey League’s Grand Rapids Griffins, has made a name for himself as one of the league’s top young goaltenders. He boasts an impressive career record of 70 wins, 33 losses, and 19 overtime losses, alongside a 2.46 goals-against average and a .911 save percentage, including eight shutouts across 123 regular-season games.

His standout performance came during the 2025-26 season, where he achieved a remarkable 26-8-4 record, a 2.33 goals-against average, and a .915 save percentage, along with five shutouts in 39 games. This exceptional play earned him a spot in the AHL All-Star Game for the second consecutive year, having also received the honor in 2025.

Although Cossa’s experience has largely been in the AHL, he made his NHL debut with the Red Wings on December 9, 2024, where he stopped 12 of 14 shots to secure his first victory against the Buffalo Sabres. Prior to his professional career, Cossa established himself as a leading goaltending prospect with the WHL’s Edmonton Oil Kings, where he recorded a stunning 71-16-7 record, a 2.12 goals-against average, and a .921 save percentage over 98 games from 2019 to 2022.

His dominance was particularly marked during the 2020-21 season, leading the WHL with a 1.57 goals-against average and a .941 save percentage. The following year, he guided the Oil Kings to a league championship, finishing the playoffs with a 16-3 record, a 1.93 goals-against average, a .919 save percentage, and five shutouts in 19 games.

Adding a personal touch, Cossa’s championship run in junior hockey connects him with current Mammoth forward Dylan Guenther, as the two were teammates during their time with the Oil Kings. Internationally, Cossa also contributed to Team Canada’s gold medal win at the 2022 IIHF World Junior Championship and previously represented Team Canada White at the 2018 World Under-17 Hockey Challenge.

Originally drafted 15th overall by the Red Wings in 2021, Cossa brings a proven record of success to the Mammoth. By quickly following the trade with a new contract, Utah has made it clear that they view this towering netminder as a vital part of their franchise’s future.
